Why are we having such trouble seeing and hearing each other?

This has been happening for several months now.  We spend about 30 minutes before each session all reconnecting, exiting the instance, rebooting systems just to be able to see and hear each other. Tonight has been especially painful, as we have spent about an hour now trying to get communication to work.  We are all on chrome, but when I try Firefox it's the same behavior.  WHY IS THIS HAPPENING?!

There is a dedicated bug thread for the Roll20 WebRTC.  Please go over there and post your: Operating System Browser and Version Description of the Issue WebRTC Debug Log (Click the "Download WebRTC Debug Log" button under the settings tab) (Be aware lhe log only exists in yours and your players browsers up until you or they refresh. So, you'll want to download the log right after you start having issues, but before anyone refreshes, to get the most useful information.)
